TECHNICAL FIELD

The present invention relates to a bed for a patient, and moreparticularly to a bed for a patient in which a drainage unit for achamber pot and a cover unit are simplified to reduce manufacture costs.

BACKGROUND ART

Generally, various beds for patients are known in the art, and thepresent invention provides an improvement of such a bed for a patient,which allows a patient to relieve nature in the bed.

A common bed for a patient includes a bed frame, protection frameslifted at both sides of the bed frame, a mattress placed in these framesfor a patient to lie down thereon, and a table rotatable at one side ofthe bed to be rotatable thereon. In addition, a mattress control handleis installed in a lower space of the bed to stand a lower or upperportion of the mattress.

However, in case that a patient not easily moving gets along on the bedfor a patient, the patient may not go to a toilet due to theinconvenient behavior and he/she should relieve nature using a separatebedpan by help of a guardian on the bed.

However, in order to solve the physiological function, many difficultiesare generated to the guardian as well as the patient to suit the bedpanto the patient.

Accordingly, various means have been proposed to solve the aboveproblems.

One example is disclosed in Korean Utility Model Registration No.306230, invented by the same inventor of this application. This utilitymodel is directed to relieving nature on a mattress, wherein a caseincluding a forward/rearward moving body provided with a chamber pot anda sealing body, which are moved forward or rearward and lifted by amoving means and a lifting means provided therein to be selectivelyinserted into a through hole formed in a mattress, is connected andfixed to a bed frame below the through hole.

According to the above configuration, the sealing body is inserted intothe through hole at ordinary times so as to give a common bed function.At this time, if a patient desires to relieve nature, he/she pushes amanipulation button, and then the sealing body descends by the liftingmeans according to the signal and then deviates from the through hole.In addition, as the moving means is operated, the moving body is movedrearward along rails provided in the case. The chamber pot is thenlifted into the through hole by means of the lifting means.

After the chamber pot is inserted as mentioned above and the patientrelieves nature, the above procedures are progressed to the contrary sothat the sealing body is lifted into the through hole. The chamber potretrieved according to the above process is than taken out by a nursefrom the side of the bed, then managed, washed and then recombined forthe next use.

However, if there is no nurse beside the patient who uses the bed for apatient, excrement of the patient is not treated until the nurse comesback, which causes bed smell in the indoor space and results inuneasiness to the patient and other persons.

In addition, a nurse should treat the chamber pot containing excrementby himself/herself as in the conventional bed. Moreover, since thechamber pot is positioned below the bed, it is inconvenient to recombinethe chamber pot to the bed after washing.

Accordingly, Korean Utility Model Registration No. 343449, invented bythe inventor of this application to solve the above problems, isdisclosed. This technique includes a bed having a mattress with athrough hole vertically formed at its center and a frame supporting themattress and including a plurality of legs; a excretion case connectedand fixed to the frame below the through hole and including aforward/rearward moving body provided with a chamber pot and a sealingbody moved forward or rearward and lifted by means of an operating meansprovided therein to be selectively inserted into the through hole; acover means provided at the front of the excrement case and having acover for sealing an upper portion of the chamber pot when theforward/rearward moving body is advanced; and a washing means forsupplying washing water to a lower portion of the cover and draining thewashing water filled in the chamber pot.

Thus, the bed for a patient configured as above allows a user to relievenature without moving hardly since the sealing body and the chamber potare linked and inserted/taken out through the through hole in a lowerspace of the mattress with the through hole by means of simplemanipulation. In particular, after relieving nature, excrement containedin the chamber pot is cleanly treated by means of the washing means, soa nurse may not treat the chamber pot directly and the indoorcircumstance may be kept agreeably.

However, the washing means includes a plurality of through holes formedin the cover, a washing water supply pipe fixed to an upper portion ofthe cover and having a plurality of nozzles inserted into the throughholes to inject washing water into a chamber pot from outside, adischarge pipe provided to a lower portion of one side of the chamberpot to discharge wasted water filled in the chamber pot, and acollecting vessel having an opening in its upper portion so that thedischarge pipe is inserted therein through the opening and to which adrainage pipe for draining out wasted water introduced through thedischarge pipe is connected.

At this time, since the discharge pipe provided to the chamber pot andthe collecting vessel connected to the discharge pipe are connected in acomplex way, manufacture costs for the washing means are too high.

In addition, since wasted water is always filled in the collectingvessel, bad smell is generated in the indoor space.

Meanwhile, as shown in FIG. 2, wherein the operating means 23 includes aforward/rearward moving unit 231 having a rail that makes theforward/rearward moving body 2 movable in the case 3 in aforward/rearward direction, a forward/rearward rack shaft 231 avertically fixed in the case 3, and a forward/rearward moving motor 231b provided with a forward/rearward pinion 231 c fixed to theforward/rearward moving body 2 and rotated in engagement with theforward/rearward rack shaft 231 a; and forward/rearward liftingoperating units 232, 233 having vertical rack shafts 232 a, 233 amounted to front and rear portions of the forward/rearward moving body 2below the chamber pot 21 and the sealing body 22 to be capable ofvertically lifting, and lifting motors 232 b, 233 b provided withpinions 232 c, 233 c fixed to the forward/rearward moving body 2 androtating in engagement with the vertical rack shafts 232 a, 233 a tolift the vertical rack shafts 232 a, 233 a.

In addition, the operating means 23 further includes a manipulationpanel 234 (see FIG. 1) provided to one side of the bed 1 to operate theforward/rearward moving motor 231 b and the lifting motors 232 b, 233 b.

Hereinafter, operation of the bed for a patient according to the presentinvention is described as follows.

As shown in FIGS. 1 to 3, when a patient relieves nature with lyingdown, the patient or a nurse manipulates the manipulation panel 234 sothat the chamber pot 21 is inserted into the through hole 121 formed inthe mattress 12, and then the patient may relieve nature.

After the patient relieves nature, the manipulation panel 234 ismanipulated so that the chamber pot 21 is deviated from the through hole121 and the sealing body 22 is inserted therein instead of the chamberpot 21. Then, the chamber pot 21 is deviated below the through hole 121and descended to the forward/rearward moving body 2, and the chamber pot21 is advanced toward the cover plate 4 by means of forward movement ofthe forward/rearward moving body 2.

Then, the insert grooves 42 formed in both sides of the chamber pot 21are horizontally inserted into the cover plate 4 provided at the frontof the case 3, which makes the upper portion of the chamber pot 21sealed.

After relieving nature, the opening/closing switch 522 fixed to one sideof the bed 1 is operated to open the opening/closing valve 521 of thewater supply pipe 51, and then washing water is supplied to the chamberpot 21 through the water supply pipe 51. The supplied washing water isinjected into the chamber pot at high pressure through the injectionnozzles 53 provided to the cover plate 4. Then, the injected washingwater pulverizes excrement contained in the chamber pot 21 and washesinside of the chamber pot. After washing the inside of the chamber pot,the wasted water passes the drainage means 6 provided to the lowerportion of one side of the chamber pot and is then discharged to awater-purifier tank through the external draining pipe 7.

That is to say, the drainage means 6 is capable of draining out wastedwater in the chamber pot 21 that is lifted and moved forward/rearward,as shown in FIG. 2. In addition, since the drainage means 6 is connectedto the external draining pipe 7 provided to the lower portion of thechamber pot 21 through the forward/rearward moving body 2 and the case 3and is composed of a plurality of length-adjustable pipes, the drainagemeans 6 is shrunken together when the chamber pot 21 is lifted or movedforward or rearward.

To describe operation of the drainage means 6 in more detail, when thechamber pot 21 is lifted, the first draining pipe 61 is lifted insidethe vertical pipe 621 of the second draining pipe 62, so the length ofthe first draining pipe 61 may be varied. In addition, if theforward/rearward moving body 2 is moved forward or rearward, thehorizontal pipe 622 of the second draining pipe 62 is moved inside thethird draining pipe 63, so the length of the horizontal pipe 622 may bevaried.

Thus, in case that the chamber pot 21 is lifted or movedforward/rearward, lengths of connection portions between the first andsecond draining pipes 61, 62 and between the second and third drainingpipes 62, 63 are varied, so wasted water filled in the chamber pot 21may be easily discharged through the drainage means 6 composed of thelength-adjustable first, second and third draining pipes 61, 62, 63.

In addition, since a plurality of packings 64 are provided to theconnection portions of the first, second and third draining pipes 61,62, 63, it is prevented that wasted water is leaked out.

Meanwhile, FIG. 4 shows an opening/closing means according to anotherembodiment of the present invention. The opening/closing means 52 ofthis embodiment includes an opening/closing valve 523 provided to thewater supply pipe, an opening switch 524 provided to an inner side of afront plate of the case 3 and operated by advance of theforward/rearward moving body 2 to open the opening/closing valve 523,and a closing switch 525 provided to the bed 1 to close theopening/closing valve 523 by manual operation of a patient or a nurse.

Thus, if a patient moves the forward/rearward moving body 2 forward bymanipulation of the manipulation panel 234 after relieving nature, thecover plate 4 covers the upper portion of the chamber pot 21. Also, atthe same time, the front portion of the forward/rearward moving body 2pushes the opening switch 534 of the water putting unit 5, provided tothe inner side of the front plate of the case 3. Thus, the opening valve523 provided to the water supply pipe 51 is opened by operation of theopening switch 534 so that the water is injected into the chamber pot 21through the water supply pipe 51.

Then, after a certain time, the closing switch 525 provided to the sideof the bed 1 is manipulated to intercept water introduced into thechamber pot 21, which completing the washing work for the chamber pot21. This gives a bed for a patient that may be more easily manipulated.
